MACHINE FOR MAKING ANTITACKS.

SPECIFICATION forming part of Letters Patent No. 630,845,da.ted August15, 1899.

Application filed December 16, 1897. Renewed February 16,1899. SerialNo. 705,693. (No model.)

"0 to whom it may concern:

Be it known that I, MAX E. BIERSACH, a citizen of the United States,residing at Milwaukee,in the county of Milwaukee and State of Wisconsin,have invented new and useful Improvements in Machines for MakingAntitacks,of which the following is aspecification.

My invention relates to improvements in machinery for manufacturing thatclass of fasteners known as antitacks, which consist of a strip of metalbent and pointed at the ends and which are used as label, stamp, or sealholders and for a variety of similar purposes.

The object of my invention is to provide adjustable mechanism wherebythe antitacks may be pointed, bent, stamped, and separated from a stripof sheet metal in a single machine having cooperative andsuccessivelyacting parts.

In the following description reference is had to the accompanyingdrawings, in which-- Figure 1 is a plan View of my invention, showingthe same as it is when in operation. Fig. 2 is a vertical longitudinalsection view drawn on line X X of Fig. 1. Fig. 3 is an elevation of thedischarge end. Fig. a is an end view of the actuating-cam of thefeedroller. Fig. 5 is a side view of the same. Fig. 6 is a plan view ofthe supporting-frame with the bed removed. Fig. 7 is a cross-section ofthe frame-bed and the adjusting mechanism drawn on line y y of Fig. 1,but with the operating mechanism removed. Fig. 8 is a left-hand sideview of the bender-head with a portion broken away to show theconstruction of the spring-actuated roller-supporting arms. Fig. 9 is aside View of the denter. Fig. 10 is a detail top View of the denter andthe die with which it registers.

Like parts are identified by the same reference-figures throughout theseveral views.

A frame 1 is provided with a bed formed in two parts or blocks 2 2, each.adjustably keyed to the frame by means of the downwardly-projectingportions 3, Figs. 2 and '7, engaged in slots 4 and arranged to be lockedtherein at any desired point of adjustment by means of bolts 6 andplates 5, the latter being arranged to engage the frame on each side ofthe slots and adapted to form a hearing for the head of the bolt. Theparts 2 2 of the bed are separated by means of a right and leftscrew-threaded shaft 7 near each end, the lock-bolts 6 being firstloosened to permit the bed-blocks to move in the slots 4. lVhenseparated, the parts are rigidly supported against vibration by means ofwedges 8, which are forced upwardly between the blocks by means ofscrews 9.

The material from which the antitacks are made consists of a strip ofmetal 10, which is fed longitudinally over the bed between thefeed-rollers 11 into the path of the formingtools, as hereinafterexplained. The bed is adjusted in each case to correspond to the widthof the strip, that portion which extends between the tools beingnarrowed to conform to the width of the uncut portion of the strip.

The tool-actuating shafts l2 and 12 are supported, respectively, fromthe bed-blocks 2 and 2 and actuated from the source of power through thedrive-wheel 13, shaft 14, worm 15, and gear-wheels 16, the latter beingkeyed to the shafts 12 and 12 v 'The initial tool comprises a cutter orpunc head 17, one on each side, which is providedwith recesses in whichthe punches 18 are removably secured by screws 19, cooperating with aholding-disk 20, bearing upon the edges of the punches to afford alateral support. The punches are provided with tapered and notched ends21, which are adapted to register in counterpart notches in a die-plate22, located in a recess in the bed. The edges of the strip 10 of thematerial are. engaged by the punches and cut to form teeth or points 23,as shown in Fig. 1, the material being moved forward intermittingly asthe teeth are out. The shafts 12 12 are also provided with bender-heads24., provided with sockets 25, in which are located arms 26, the latterhaving studs 27, which engage in slots 28 in the head to retain the armsin the sockets, with springs 29 adapted to hold the arms normally withthe studs engaging the outer ends of the slots. The arms are provided attheir outer ends with antifriction-rollers 30, which engage the points23, formed by the punches in the material, and bend them downwardly, asshown in Fig. 1. After the points are bent downwardly they are creasedor crimped longitudinally by means of a crimping-punch 31, whichregisters with a die punches as soon as their supporting-rods arereleased by the actuating-rollers.

The material aft-er leaving the punches is passed under a printing-plate36, which is actuated as hereinafter explained, and over the shear-bar37.

38 is a separating-knife pivoted at 39 and provided with an extended arm40, which is connected by a retracting-spring 41 with the floor or othersuitable point of support to holdthe knife normally in a position withits edges above the shearbar. A downward movement is intermittentlycommunicated to theknife from the shaft 12 through the eccentric 42 androller 43, the latter being sup: ported on a trunnion projecting fromthe front end of the knife-blade. The downward movement of the knifeseparates the antitacks from the strip 10 of material, cutting the sametransversely between the successive The points 23, which are formed inits sides. knife having completed its downward movement, it is returnedto its normal position by theretracting-spring 41.

The motion of the knife-arm 40 is communicated to the printing-platethrough the adjustable connecting-rod 44, lever 45, stud 46,vertically-sliding plate 47, spring 48, and supporting-plate rod-49, theplate 47 being supported in a frame 50, projecting upwardly from thebed. The lever 45 isprovided with a slot 51, in which the stud 46engages, thus permitting the plate to slide freely in 'the bracketithout cramping. The motion of the lever 45 is also communicated to aninking-roller 52 through the stud 46, sliding plate 47, lug 53, link 54,and curved lever, 55, the latter being pivoted at 56 to the frame 50.With the extreme movementof the lever45 downward upon the lug 46 theprinting-plate 36 is forced downwardly and the inking-roller is carriedoutwardly over the rotary ink-supply plate 57, and with thereversemovement of said lever the printing sary that the feed should beintermittent, and for accomplishing this result I have provided theshaft12 with an eccentric plate 59, which bears at intervals upon the roller60, located on one arm of an elbow-lever 61, the motioii of which iscommunicated to the lower feedroller 11 through the rod 62, crank 63,pawl 64, and ratchet 65, the motion being regulated by the proportion ofthe parts to correspond in time with the intervals between the action ofthe tools and in distance to the width of the finished antitacks.

66 is a retracting-spring for withdrawing the rod 62 and its connectedparts after the movement caused by the eccentric plate 59 iscompleted.

It will thus be observed that the strip of material as fed by thefeed-rollers is punched to form the tack-points, the pointed ends bentby the rollers of the bending heads and crimped or dented by thedenters,the uncut portion of the material stampedby the printer, and thenseparated by the knife betweenthe successive points to form thecompletedantie tacks ready for the market. Allthe toolsare actuated fromthe two shafts 12 and 12'1il1 such a manner as to cooperate eachwiththeother in an intermittent simultaneous action. upon the various parts ofthe Work. The bed. being adjustable, I am enabled to usethe. same devicefor strips of differentv widths by substituting feed-rollers, printingmechan= ism, cutting-knives, &c., of the proper size; to correspond withthe widthof the strip and the size of the antitackstobe formed.

While I have shown and described the various parts of. the printer andprinting mechanism in the construction used, I do not claim the specificconstruction thereof in. this ap, plication, as this construction maybeindependently used for other purposes, and; I therefore expresslyreserve the. same as the subject-matter of a future application.
